NV4500 swap! Find an Nv4500 out of a 1994-1997 dodge 2wd truck. Get an adapter plate from Advanced Adapters (Note the adapter will need further machining to fit your bellhousing). Turn down the snout of the bearing retainer on a lathe to match the diameter of your exhisting bearing retainer. This allows you to use your stock throwout bearing. Or talk to Advanced Adapters as they will have a crossover bearing to work with your fork. Bolt adapter to bellhousing and transmission to adapter. Cut new hole in raised floor section approximately 6 inches back from existing hole. Have driveshaft shortened or new shaft made. Drive around with a smile on your face with a 5 speed fully syncromeshed transmission that has a granny low gear (5.61:1) and an OD gear (0.73:1)
Of course this is an oversimplified version of the swap. Do a search for more details. Of course I wouldn't reccomend an OD in a 3/4 ton with a splash 216 or 235. A full pressure 235 or 261 would have my blessing.
